12:28 AM CDT Update: About 1.5 miles have been surveyed so far (out of an estimated path length of probably around five miles). The small portion surveyed so far is along Schochoh Road just northeast of Adairville. So far, the path width is 300 yards, with maximum winds of 135 mph making it an EF2 tornado. There are three known injuries, all non-life threatening. Several livestock were killed, including several horses that will likely need to be put down. One home was completely demolished, three houses were damaged to the point of being uninhabitable. Numerous outbuildings were destroyed. Three very large grain bins were destroyed and blown up to a quarter mile downstream. Again, this is very preliminary. We are passing information along to you as soon as we get it from the field surveyors.

Previous Information

A National Weather Service storm survey team was available to make a trip down to Logan and Simpson counties to make a preliminary assessment of the tornado that struck around 2 PM CDT Monday afternoon. With daylight fading quickly, they have been able to determine that the tornado at least caused EF2 damage. The survey will continue Tuesday morning, with visits to other damage sites across south central Kentucky possible.

The images below indicate what the Nashville radar showed as the tornado crossed the Logan/Simpson county line. The first image shows a measure of the power reflected back by hydrometeors in the storm (with reds/purples/whites indicating heavy rain/hail). The second image shows the radial winds from that storm. The green colors indicate winds coming toward the Nashville radar (located to the south in the image), whereas red colors indicate winds going away from the Nashville radar. The tornado is where the two bright green and red colors are right next to each other, indicating rotation.

We expect to add more data as pictures come in. Additional storms developed across the region Monday afternoon. Here are some pictures that have been sent in to the office:
